Leiomyoma originating from the scrotum is a scarce entity. We report
a case of scrotal leiomyoma which was unique to us. A 35 year-old
man sought medical care for a painless scrotal lesion that had
enlarged over a 3-year
period and was causing him discomfort. His medical history was
otherwise unremarkable: there was no history of trauma, inflammation,
or infection,
and no significant urologic antecedent. Physical examination revealed
a 2x2 cm painless skin-colored nodule of rubbery consistency on
the left side
of the scrotum, which was well circumscribed, pedunculate and clearly
separate from the testicles and epididymis. There was no
inguinal lymphadenopathy.
Scrotal ultrasonography demonstrated that the scrotal contents
were normal. Under local anesthesia, the scrotal mass and surrounding
skin were surgically
resected. Histologic examination was consistent with leiomyoma.
There was no evidence of cyto-nuclear atypia. The patient's postoperative
recovery
was uneventful. On follow-up visit 10 days later, he did not have
any complications, and the sutures were removed. At his last visit
12 months after the procedure,
he was still asymptomatic and did not have any recurrence. Leiomyoma
is a benign tumor of smooth muscles that may arise anywhere in
the body. Smooth
muscle tumors of scrotum were first described by Forsters in 1858.
They arise from the dartos muscle and are extremely rare: less
than 50 cases were reported in the literatures. Patients usually
present with
painless
solitary small cutaneous lesion, and that's histology which confirms
the diagnosis. Treatment is based on a simple surgical excision.
Exceedingly rare, scrotal leiomyoma are usually misdiagnosed. Thus,
this entity
should
be suspected in cases of scrotal masses.
